Rearrange the equation so q is the independent variable. −7q+12r=3q−4r

Mathematics
1 answer:
Alenkasestr [34]3 years ago
7 0

Answer:

q=8/5 r

Step-by-step explanation:

Step 1: add -3q to both sides

-7q+12r+-3q=3q-4r+-33

-10q+12r=4r

Step 2: Add -12r to both sides

-10q+12r+-12r=-4r+-12r

-10q=-16r

Step 3: Divide both sides by -10.

-10q/-10=-16r/-10

q=8/5r

Robin Cline is a computer analyst. Her annual salary is $52,789. What is her monthly salary? *
Helen [10]

Answer:

<h2>$43999.08 per month</h2>

Step-by-step explanation:

step one:

We can calculate her monthly salary by dividing her annual salary by 12

given that her annual salary is  $52,789

so we divide  $52,789 by 12,

step two:

Note: we are dividing by 12 because in a year we have 12months

so  $52,789/12

=$43999.08

step three:

from the division, we can see that in a month Robin Clines monthly salary is  

$43999.08 per month

List the domain and range of (5,12)(3,-3),(-2,7)(2,12)(5,1)
Sliva [168]

Answer:

Domain={-2,2,3,5}

Range={-3,1,7,12}

Step-by-step explanation:

The given ordered pairs are (5,12)(3,-3),(-2,7)(2,12)(5,1).

The domain refers to the set of all the first coordinates(x-values).

Domain={-2,2,3,5}

The range refers to the set of all the second coordinates (y-values).

Range={-3,1,7,12}

Note that, we do not repeat elements in a set.

Do not list the 5 in the domain twice.

The same applies to the 12 in the range

What is the slope of a line perpendicular to the line whose equation is 4x−10y=404x−10y=40. Fully simplify your answer.
Anna007 [38]

Answer:

-  \frac{5}{2}

Step-by-step explanation:

4x -10y= 40

Let's rewrite this equation in the slope-intercept form (y= mx +c) so that we can obtain it's slope.

10y= 4x -40

Divide both side by 10:

y =  \frac{2}{5} x - 4

The product of the gradients of perpendicular lines is -1.

⅖(gradient of line)= -1

Gradient of perpendicular line

=  - 1 \div  \frac{2}{5}

=  - 1 \times  \frac{5}{2}

=  -  \frac{5}{2}
